Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00060 | $0.00324 |
| Opus 5 | $0.00030 | $0.00162 |
| Sonnet 5 | $0.00012 | $0.00065 |
| Haiku 4.5 | $0.00006 | $0.00032 |
Grade A, and why
jellyfin-mcp-operations scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
78% identical to gitlab-api-operations — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Jellyfin Mcp Operations
Use the provider's governed MCP tools through GraphOS delegation.
Workflow
- Establish the verified GraphSession and tenant before discovery or retrieval.
- Discover the current condensed tool surface; never assume a stale tool name or schema.
- Prefer read-only inspection first. For changes, present impact and use the provider's dry-run or preview mode when available.
- Execute mutations as fenced WorkItems so retries remain idempotent and auditable.
- Ingest source data only through the signed connector preset and ChangeEnvelope path.
- Verify the durable result and its trace/evidence before reporting completion.
Safety contract
- Never persist credentials, endpoints, raw personal identifiers, hostnames, or local paths.
- Resolve TLS trust and verification from environment/configuration; never hardcode bypasses.
- Treat unknown ACL, tenant, schema, or tool-contract state as a hard failure.
- Require explicit approval for destructive, externally visible, or irreversible actions.
- Keep runtime traces policy-scoped and privacy-sanitized.
Specialized workflows
Read the workflow catalog only when the request needs a provider-specific procedure, parameter map, script, or reference asset.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

jellyfin-mcp-operations is a skill published in the GitHub repository Knuckles-Team/jellyfin-mcp (3 stars, last pushed 15d ago), licensed MIT. It adds 60 tokens to every session and 324 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 78% identical to gitlab-api-operations, differing in 6 lines, and is treated as a copy.
